AJAX execution failed
You get an error like:
or
Main Cause
The domain you’re using doesn’t match the one set in Preferences > SEO & URLs in PrestaShop.
This triggers a security restriction in the browser (cross-domain request), which blocks the AJAX call.
Example
- URL used to log in:
http://mystore.com/admin - Configured domain in PrestaShop:
http://www.mystore.com/admin
✅ Solution: Always use the exact URL configured in your shop settings.
Other Possible Causes
1. Hosting Restrictions (e.g. OVH)
Some hosts block AJAX scripts by default.
➡ Follow their guide on file/folder permissions:

2. Store in Maintenance or Inaccessible
The module only works if the front-office is live and accessible.
➡ Disable maintenance mode or fix redirection issues.
